Coug , unless your shoot'n a 26 series shaft , hes got no chance

RE: Going to have a duel with bows/arrows.
 

Sounds like fun.

A brand new un-wounded yellow jacket with each new hole marked would rule out the arrow that achieved increased penetration due to sliding in an old hole.

Arrow size x arrow weight x arrowspeed= how much penetration

Is this the contest equation?

I'm not sure draw length would be a factor since thespeed variable is being obtained. Unless overall power stroke placed into the arrow affects it's down range trajectory or something like that. Doubt it though.

Let us know how it goes, it will give us something to ponder until deer season rolls around anyways. Nothing like a dual!!

RE: Going to have a duel with bows/arrows.
 

regardless, those arrows he's chosen have the spine shot out in 5 flings of each arrow.

Can't wait as well Coug.

RE: Going to have a duel with bows/arrows.
 

If you want to prove it to him scientifically, just use the following equation:

Kinetic Engergy = 0.5*[(weight or arrow in grains/7000)/32.2] * (speed in fps)^2

That gives you your energy in foot*pounds. Then, you can divide that by the frontalarea of the respective arrows to get foot*pounds per square inch. This will have a direct relation to penetration.

I had to edit this b/c I left out dividing the weight by 32.2 to get the units to mass instead of weight. Sorry if I messed anyone up with that.

Cougar, this ain't fair buddy! You dangle something like this in front of our faces then tell us it's gonna bea while???? [&:][&:][&o] WTH?? I mean, offer me a T-bone and toss it in the freezer why dontcha? Sheesh..... :D

I'm sure you will, but test at different yards, not just up close. Because, if I am thinking correctly, up close he should be pretty close to hangin right w/ ya. But out a little farther is where it will really show up. Stick it to him. Let us know.

You math guys make my brain hurt! :D

RE: Going to have a duel with bows/arrows.
 

The true results won't be TRUE. You're comparing apples and oranges you know with the different weights. OH well,let the games begin. You should definitely make sure you do down range measurements. By that I mean longer distances. You'll maintain a lot more momentum than he will, or is that crap, or is it speed or is it crap or is it momentum or is it kenetic energy or is it force or is it.... who wants a beer. Pass the popcorn.

RE: Going to have a duel with bows/arrows.
 

I forgot in my original equation to divide by the acceleration of gravity to get the units right, but edited it if you want to see it correct now. Sorry for any confusion.

Anyway, basically it comes down to this... With the weights you gave he would have to shoot a speed1.19 timesthat of your speed. So if you are shooting 250 fps he will need to shoot298 fps to be even with you as far as KE goes.

Sorry I am getting technical, but Ido ballistics analyses for a living so I get all geeked out about stuff like this.

Disclaimer - I am a nerd.

Huntingson, Don't forget that the lighter shaft is going to shed that kinetic energy faster when it impacts the target. Given that the KE's are close to each other, the heavier shaft carries more momentum and that's what's going to tip the scales and win the day for Cougar!

Cougar, The results from the bag target are going to be useless. There is too much variation in the density of the target from point to point. You need a target with more uniform density. I'd suggest using the Morrel for both field point and broadhead tests. (Turn it around from one side to the other when you change heads.)

I forwarded the idea on to Myth Busters!
